The U.S. Census Bureau released its April 2026 Monthly Construction Spending report on June 1, 2026, and the headline figures project stability: total construction spending reached a seasonally adjusted annual rate of $2,172.4 billion, up 0.4 percent from the revised March estimate of $2,164.5 billion and 0.9 percent above April 2025. For the first four months of the year, total spending reached $657.2 billion, barely ahead of the $656.1 billion recorded in the same period of 2025. The top-line numbers suggest a construction market in modest equilibrium. The sector breakdown tells a more complicated story.

Data Centers: The Structural Engine

The clearest signal in the April data is the dominance of data center construction. According to an Associated Builders and Contractors analysis of Census Bureau data, spending on data center construction has boomed 28.1 percent over the past year, reaching a seasonally adjusted annual rate of $50.7 billion in April. ABC Chief Economist Anirban Basu put the situation bluntly: "Private sector construction momentum has been difficult to find outside of the still-ascendant data center segment." Nonresidential construction spending ticked up just 0.1 percent month over month, and private nonresidential construction fell 0.2 percent from March's revised estimate of $731.0 billion to $729.8 billion in April.

The data center boom is directly driving the only other major growth category in nonresidential private construction: power infrastructure. KPMG's analysis of the April report found that spending on power construction climbed 6 percent over the year as utilities expand capacity to meet data center demand. "Together, data centers and utilities account for almost all the work in nonresidential construction," KPMG's economists noted. The firm added a pointed observation: "Given the rise in costs, the amount of construction spending is contracting" — meaning that after adjusting for construction cost inflation, real construction activity is declining even as nominal dollars hold steady.

Manufacturing Construction: A Sharp Retreat

The most consequential decline in the April data is in manufacturing construction. Construction Dive reported that spending on manufacturing projects fell 1.2 percent month over month in April and is down 18.4 percent over the past year. This represents a significant reversal from the 2023–2024 manufacturing construction surge, which was fueled by the CHIPS Act semiconductor fab buildout and Inflation Reduction Act clean energy manufacturing incentives. Many of those megaprojects have now moved past peak construction spending, transitioning from earthwork and structural phases to interior fit-out and commissioning — phases with lower monthly spend rates. The manufacturing construction peak is normalizing, not collapsing, but the year-over-year comparison is striking.

KPMG noted that manufacturing construction "remains the largest nonresidential category, but utility construction is closing the gap fast." As the data center and power pipeline continues to scale, the relative share of manufacturing in nonresidential construction spending is shrinking even though the absolute dollar volume of manufacturing projects in the field remains substantial. For contractors whose backlogs were built on the semiconductor and battery manufacturing wave, the transition to the next major category — AI and grid infrastructure — is now an operational imperative.

Public Construction Holds Firm

The Census Bureau's April 2026 report shows public construction spending at a seasonally adjusted annual rate of $532.7 billion — up 0.4 percent from March's revised estimate of $530.6 billion. Highway construction reached $149.6 billion at an annual rate, up 0.4 percent from March, supported by the ongoing deployment of Infrastructure Investment and Jobs Act formula funding through state departments of transportation. Educational construction reached $113.7 billion, up 0.6 percent from March. Basu described the overall dynamic: "Nonresidential construction spending inched higher in April, but that growth was entirely due to a sizable increase in public sector activity."

The composition of public construction growth reflects the geographic concentration of active infrastructure programs. According to ConstructConnect's May 2026 regional construction starts analysis, civil work is strongly favoring coastal markets: the Middle Atlantic division is up 98.7 percent year-to-date through April, and the Pacific division is up 72.7 percent, reflecting significant infrastructure commitments in those regions. In sharp contrast, the four Central Census regions are facing stalling activity or outright declines, meaning infrastructure investment is flowing to a limited set of geographic markets and leaving much of the nation's interior lagging behind.

Residential: Stability With Single-Family Softness

On the residential side, the Census Bureau reported spending at a seasonally adjusted annual rate of $909.9 billion in April, up 0.8 percent from March's revised estimate of $902.9 billion. The residential market is providing a stabilizing floor to total construction spending even as nonresidential private activity softens. However, April 2026 housing starts data released May 21 showed that single-family starts have been declining as builders face persistent affordability headwinds from high mortgage rates — with the 10-year Treasury near 4.2 percent and the Federal Reserve signaling at most one rate cut late in 2026.

The Real Picture: Inflation-Adjusted Activity Is Shrinking

The sharpest analytical point in the April data comes from adjusting for cost inflation. Construction input costs are up 4.4 percent from a year ago based on the producer price index for nonresidential construction inputs, and far more for key materials: diesel fuel up 51 percent, steel mill products up 15 percent, aluminum mill shapes up 34 percent, and copper up 21 percent year over year, according to ConstructConnect's analysis of BLS and AGC data. When nominal spending growth of 0.9 percent year over year is measured against input cost inflation running at multiples of that rate, the construction sector is effectively building less — in volume terms — than it was a year ago.

This is the defining tension in the mid-2026 construction market. The dollar value of work is holding. The physical volume of construction activity is declining. For contractors pricing work today, the gap between nominal spending numbers and real-world cost experience is not just an academic distinction — it is the central challenge of every bid, every contract, and every project budget in the current environment.
